The technical requirements for the manufacture of products and functional materials used in products are becoming more and more sophisticated as the need to reduce the burden on our natural environment becomes increasingly evident. Kao maintains cooperation between a wide variety of divisions as it pursues stable production, high quality, and lower costs. Our R&D work includes reaction, separation and purification, and formulation technology. More specifically, we focus on processing technologies such as encapsulation and transformation of small particles that add value to products, assembly and processing technologies that combine different functional materials in products such as diapers and various sheets, and the construction of "green" processes and intelligent manufacturing systems. All of these R&D activities are actively pursued from a global perspective.
